TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are one of the most common components used in electronics, and they are used to protect circuits from high voltages or transients. They are designed to limit the amount of current that can flow through them when a voltage is applied, preventing overload conditions from damaging any connected components. The P6KE39A R0G is a commonly used TVS diode, which is designed to protect sensitive circuits against voltage transients commonly caused by induced lightning or power station surges.The P6KE39A R0G is constructed as a two-element device with a pair of silicon rectifiers. It is composed of a zener diode and a trigger diode. The zener diode is designed with a breakdown voltage of 39 volts, while the trigger diode is designed to start conducting after a voltage of 18 volts is applied. When the transient voltage is above the trigger voltage, the diode starts to conduct and limits the current.The main application of the P6KE39A R0G is in sensitive electronics applications, particularly for protecting against destructive voltage spikes caused by high voltage transients. It is commonly used in systems such as computers, cell phones, and medical equipment to protect the circuits and devices from accidental damage or short circuits caused by overvoltage conditions. It is also used in power switches, relays, and circuit protection devices.The P6KE39A R0G can also be used in multiple element circuits to provide better protection from voltage transients. It is often used in combination with other diodes, capacitors, or resistors to create a multi-stage protection circuit. It can also be used in series arrays to increase the number of breakdown voltages.The working principle of the P6KE39A R0G is demonstrated in the diagram below. When a voltage is applied, the zener diode breakdown voltage is reached, causing the diode to enter the breakdown region and start conducting. The trigger diode then has a voltage drop across it, which causes it to start conducting. This prevents the current through the zener diode from exceeding the maximum current determined by the breakdown voltage. In this way, the voltage spike is suppressed and no damage is caused to the connected components.The P6KE39A R0G is a popular device that provides reliable protection against voltage transients. It is commonly used in many electronics applications to safeguard against damaging overvoltage conditions. With its two-element construction and easy circuit design, this diode offers reliable protection and is often preferred for its high reliability and cost-effectiveness.
